Geotechnical properties of some organoclays
Sadhana, 2013 The engineering characteristics of clay are dependant on its mineral and chemical structure. When the clay soils interacted with water, their volume and shear strength and compressibility properties change gradually. Large amount of decrease in terms of the shear strength of clay soils due to swelling is observed.

A thermoanalytical assessment of an organoclay [PDF]
Journal of Thermal Analysis and Calorimetry, 2011 High resolution thermogravimetric analysis (TG) has attracted much attention in the synthesis of organoclays and its applications. In this study, organoclays were synthesised through ion exchange of a single cationic surfactant for sodium ions, and characterised by methods including X-ray diffraction (XRD) and TG.

Coloration Technology, EarlyView.Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

Electroanalysis, Volume 38, Issue 11, November 2026.This study examines the use of uric acid (UA), a naturally occurring redox‐active molecule, as a reporter for aptamer‐mediated electrochemical signal transduction. Five graphite‐sheet electrode configurations were compared, with the multiwalled carbon nanotube/carbon paste‐modified graphite sheet electrode (MWCNT/CP/GSE) providing the strongest overall

Iraqi Journal of Chemical and Petroleum Engineering, 2017 Calcium-Montmorillonite (bentonite) [Ca-MMT] has been prepared via cation exchange reaction using benzalkonium chloride [quaternary ammonium] as a surfactant to produce organoclay which is used to prepare polymer composites.

SPE Polymers, Volume 7, Issue 4, October 2026.SEM images of unmodified (U30) and TESPT‐grafted (U30‐SCA) silica compounds show that pre‐grafting eliminates agglomerates. Stress relaxation data fitted with a constrained five‐element Weichert model give discrete relaxation times (τ1$$ {\tau}_1 $$‐τ5$$ {\tau}_5 $$), both reduced by grafting. Their ratio, the Filler Network Index (FNI = τ1$$ {\tau}_1 $

Dynamic mechanical characterization and modelling of polypropylene based organoclay nanocomposite
EPJ Web of Conferences, 2015 In order to investigate the dynamic behaviour of polypropylene based organoclay nanocomposite, the polypropylene matrix and a master batch of polypropylene modified anhydrid maleic were mixed by means of melt mixing technique.

eXPRESS Polymer Letters, 2014 Cyclic butylene terephthalate (CBT®) is an interesting matrix material for the preparation of nanocomposites due to its very low, water-like melt viscosity which favours clay exfoliation. Nevertheless, polymerized CBT (pCBT) is inherently brittle.
